Typical Submersible Pump Installation
TO SERVICE
RELIEF VALVE
The water system tank should be installed as close as
possible to the pressure switch (24 inches or less) to reduce
the adverse effect of friction loss and elevation differences.
1.
Disconnect electric power.
2.
For installations replacing an existing water tank, drain

installation this step is unnecessary.
3.
Locate the water system tank on a firm, level surface with
adequate drainage. Typical installations are shown in the
following section.
MULTIPLE TANK INSTALLATION PROCEDURE
Water system tanks can be connected together to increase the
supply of usable water (drawdown). Two tanks of the same size
will double the supply and three tanks will triple the supply. When
using a high capacity pump, the manifold and pressure switch
assembly must be installed in the pipe line as close to the center
of the tanks as possible. Manifold and main should be 2 times
the size of the feederline.

exceeding a working pressure of 125 psi (typically
submersible pumps),install a pressure relief valve (rated at
125 psi or less, but greater than turn off pressure) in the
system near the tank. The valve should be the same pipe
size as the tank outlet. This necessary on tank-mounted jet
pump units.
5.
Connect tank to the pump discharge line using the same
size pipe as the pump tap, or larger. WARNING: Hold 90°
tank street elbow with wrench when threading and tightening
connecting pipe.
6.
The tank should be flushed 5 times prior to household
use, see Operation section.
